Key gap in antigen testing protocol prompts rethink

On Thursday, the Delhi government directed all districts in the Capital to ensure no lapses take place in testing people with symptoms of the coronavirus disease (Covid-19) through the Reverse Transcription-Polymerase Chain Reaction procedure, considered the most accurate method of detecting the viral infection.
While experts suggest that if RATs must be used, those symptomatic individuals who test negative must undergo a RT-PCR test (or another accurate molecular test), this is not foolproof either -- at least 40% of those infected with Sars-Cov2 are asymptomatic.(HT Photo)
